Also, you might consider reducing the size / prominence of that large area of blue in the top center. As it is, it's visually weighty enough to serve as a second focus that prompts viewers' eyes to rest there. If you move the wisp of cloud separating the two darker blue areas of sky a bit to the left, the clear sky would appear more as a field extending up past the top of the picture. The visual thrust of the image would be less bounded, which I think would fit it better.
